 hsc2hs gets built in stage0 and stage1. The stage0 binary is used during
 the build, and the stage1 binary is the one that get released.

 The hsc2hs that gets built in stage0 is used during the build in both in
 stage0 and in stage1. Currently some options specific to the platform are
 encoded into the hsc2hs wrapper script (inplace/bin/hsc2hs) in a variable
 called HSC2HS_EXTRA. The problem with this is that in stage0 and stage1 we
 need different options.

 The solution is very simple: Just don't put these options into the stage0
 wrapper. The build system passes the right options for whatever stage it's
 up to anyway when it invokes it.
